You might as well asked for a manual on world peace! It's a tricky, artful process to make molds on this scale on a normal person budget. I've made a few on a considerably smaller scale and you can see some of it here (you have to read from the bottom up since the posts are chronological).

If I were doing it and intending to build only one boat, I would consider using a strip foam planking method like Ian did on his LR series of a-cats. The process would be the same for you - only the number of layers of fiber would need to increase and you probably need a little more structure in the hulls (including a sub-deck to help with spinnaker and forestay loads). I can't help with the exact lamination schedule but perhaps the Man Shed can shed some light relative to the trimaran he's building.
